A stationary rotating slingshot with an optional lock. This machine will use a basic wheel and axle to allow the slingshot to rotate and you can jam the machine for lock.
We will require:
•Wooden axle (with cylinder hole for lock)
•Wooden wheel (with cylinder hole for lock)
•Y shaped stick
5 Elastic bands
•Pouch
•Foam (for ammo)
•Rod (for locking mechanism)
•Glue
Instructions:
•Find a Y shaped stick to use as slingshot
•Sticky tape elastic bands on to Y shaped stick.
•Stick sticky-tape to elastic bands (use as pouch) (this becomes what is known as the slingshot)
•Connect slingshot to axle with military standard glue.
•Place axle in wheel
•Place wheel on horizontal surface
1.Rotate slingshot.
2.Pull back elastic bands.
3.Aim
4.Load slingshot
5.Lock slingshot so it doesn't rotate
6.Fire
1.How does your model give an example of force acting on an object?
Gravity acts upon ammo to make it arc down to the ground once fired.
2.How does your model give an example of energy transferring?
The motion energy of the elastic bands transfers to the ammo to make it move.
3.How does your model give an example of energy transforming?
The potential energy of the elastic bands transforms in to motion energy.
